fenglaiyang , via OnePlus 9 , Apr 17, 2021 : I have the OnePlus 9, and after using it for almost a month now, it's already having some issues. I notice that sometimes theres dramatic lag time when I click the power button to turn my phone on. I would click it, and it would delay for 2 + seconds until it turns on for me to do the fingerprint scan or the pattern unlock. And this continues intermittently for maybe an hour or so until eventually, clicking the power button, holding the power button (as if I were to reset the phone) and tapping the black screen doesn't even turn the screen on, and it eventually completely restarts itself, as evidenced by the red and white animation showing on the screen during the rebooting/restarting process. This has happened on day 1 of getting the phone, but I thought it was just tryna get used to the apps and everything I had backed up and added from my previous phone. Is this happening with anybody else who has a oneplus 9 ? It gets really annoying because what if I have an emergency, and I need to get on my phone ASAP, and then it happens and my phone doesn't turn on for the next 5 minutes or so. Is this possibly a UI problem? Or is it possible it's just my device?
